    The idea behind this channel, to learn technology with animation (not with images), so everyone can easily understand, clear the concept, and can creak the interview. For suggestion and feedback, please feel free to write in the comment section. If you like my work please like and subscribe to the channel for more videos.

    Please make a video on How to design a 1000 km dwdm link.i mean what all would be the requirements, how many Amplifiers, oadms etc will be used.

    Your formulas look reversed: Symbol rate = Bit rate/number of bits per symbol. Also, the Raw BW = Bit rate/(number of bits per symbol * Polarization)

    • @OpticsTrans
      @OpticsTrans  3 ปีที่แล้ว

      Thanks for your comment.
      To calculate BW, need Baud rate (symbol rate per second, in one second how much data transmitted) example- 32GBaud , in one second 32G transmitted.
      Then how many bits in one symbol example 8QAM - 3 Bits
      So BW transmitted in one second = 32*3 = 96G
      Depends on Polarization if single total BW is 96 G if dual 96*2 = 192G
      Hope this clear, please feel free to share your suggestion/feedback.

    • @sunnyboy866
      @sunnyboy866 3 ปีที่แล้ว

      @@OpticsTrans No that's not the BW. In your example, 192G is the datarate and 32G is the Baudrate or symbol rate. BW is related to the baudrate which is the switching speed of the signal.

      @@sunnyboy866 192G is the datarate , No, its RAW BW using dual-polarization (maximum amount of data that can be transferred per second on a link).
      Data rate (speed of data transmission) 150G, channel is transmitting 150 Gbps data per second on one pol. mode.

    • @sunnyboy866
      @sunnyboy866 3 ปีที่แล้ว

      That's wrong. Bandwidth is related to the symbol rate and not the Bit rate. E.g 100G DP-QPSK require electronics to work at 25GHz and not at 100G

    • @OpticsTrans
      @OpticsTrans  3 ปีที่แล้ว +1

      @@sunnyboy866 What the BW in your example?. as per my understanding
      25Gbaud rate, QPSK(One carrier carry 2 bits) , with dual-pol. 4 bits per symbol and getting 100G
